JAMES A. ROBERTS, OF SYDNEY, NEW SOUTH WALES, AUSTRALIA.

CARRIAGE-LAM P.

SPECIFICATION forming part of Letters Patent No. 223,389, dated January 6, 1880.

Application filed June 1 1, 1879. Patented in England, October 12, 1878.

To all whom it may concern Be it known that 1, JAMES ALFRED B0B- ERTS, of Sydney, New South Wales, Austialia, have invented a new and useful Improvement in (larriage'Lamps, of which the following is a specification.

My improvement relates to the candle-tubes of carriage-lamps, and the object is to facilitate the insertion of the candle into, and its removal from, the candle-tube.

The invention will be more particularly described with reference to the accompanying drawings, wherein- Figures 1 and 2 are perspective views of carriage-lamps with candle-tubes. Figs. 3 and 4 are vertical sections of the candle-tubes with the cap shut in Fig. 3 and raised in Fig. 4. Fig. 5 is a plan view of Fig. 4.

Similar letters of reference indicate correspondin g parts.

a is the candle-tube, on the head of which is a collar or flange, b, to which the nozzle or come 0 is hinged at d. The said hinged nozzle or cone 0 is perforated at its center for the passage through it of the candlewick.

6 is a lip or flange on the front of the noz zle or cone 0, which lip, when the nozzle is shut down, projects beyond the collar or flange b. The said lip is formed with a hole that is threaded to receive the binding-screw f.

'In the candle-tube is recess g, for receiving the end of the binding-screw f, which screw may be entered when the nozzle or cap is closed, and in place of arecess a projection or lip may be formed on the candle-tube, beneath which the screw will take.

When it is wished to introduce a candle or withdraw it, the screw f is to be turned to free its end from the hole g, thereby releasing the cone, which may then be turned on its hinge d to open the candle-tube, as represented in Fig. 4.

After a candle has been introduced it is only necessary to shut down the hinged nozzle 0 upon the collar or flange b, and screw home the binding-screw, as illustrated in Fig. 3, and

the hinged nozzle will be fixed and the candle secured.

A spring-snap fastening or other analogous device may be used for fastening down the nozzle 0 in place of the screw f.

The reflecting-surface of the interior sides of the lamp represented in Fig. 1 consists of a series of tapering angular corrugations, (marked 7th,)tl16 surface of the reflector having the figure produced bya series of tapering triangular prisms placed edge to edge, as shown clearly by the frontend of the side reflecting-surface. (Shown in Fig. l.) The tapering angular corrugations h increase gradually in width from the back to the front of the lamp, as shown.

\1 The back reflecting-surface iand the reflector k at the back of the lamp are also made with angular tapering corrugations, which are arranged radially, as represented.

Instead of making the corrugated reflecting surface of the lamp of the angular or prism like form represented in Fig. 1, it, may be made as a series of curved concaved flutes or corrugations with like efiect. This construction is represented in Fig. 2 applied to a lamp having a cylindrical body and an open front, the curved, concaved, corrugated, or fluted reflecting-surfaces being marked l l and m m.

The reflecting surface Z of the cylindrical body is conical, and the flutes or corrugations taper from front to back. The reflecting-surface m at the back is formed with similar tapering flutes arranged radially, as represented.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent- The combination of candle-tube a, having recess 9 and flange b, the centrally-perforated cone 0, hinged to said flange at d and having lip e, and the binding-screw fiworking in threaded hole of said lip, as shown and described.

JAMES ALFRED ROBERTS.
